Frequently Asked Questions
How do I know whether a 20x25x1 filter will fit my HVAC?
Measure the actual filter slot and the old filter before ordering. Many listings show a nominal size but include the actual dimensions (for example 19.5 x 24.5 x 0.75 in). Compare those actual dimensions to your slot to avoid a loose fit or a filter that's too thick.
What MERV rating should I choose for a home with pets or allergies?
MERV 11–13 is a good balance for homes with pets or allergy sufferers: it captures smaller particles like pet dander and pollen without the heavy airflow penalty of very high MERV filters. Always confirm your HVAC can handle higher-MERV filters to avoid performance issues.
Are washable electrostatic filters better than disposable pleated filters?
Washable electrostatic filters (reusable) can save money over time and reduce waste, and many users report good airflow and fit. They do require routine cleaning and inspection. Disposable pleated filters offer convenience and predictable filtration levels; choose based on your willingness to maintain a washable option and the specific filtration needs of your household.
